so far, so good at DOI.. but now I feel like I am waiting for the other shoe to drop! DOI has a FB page, but employees cannot access FB at work. Sometimes I can get through to Twitter, sometimes not. LinkedIn is an essential tool for professional networking and all the other reasons stated below. through LinkedIn I have connected to people who I have found to be friendly, helpful and engaging, and have included them in events in our native non-profit organization. This only helps to expand and strengthen our organization, (SAIGE) which provides training in Indian issues for federal, state, tribal and local government employees.
